HASP.

Specification of Letters Patent.

Patented Sept. 15, 1908.

Application filed April 2, 1908. Serial N 0. 24,769.

To all whom it may concern."

Be it known that I, JOHN CHRIsTENsoN, a citizen of the United States, residing at Northport, in the county of Stevens and State of Washington, have invented a new and useful Hasp, of which the following is a specification.

This invention relates to im rovements 1n hasps andhooks, such as are tted to doors, gates, and so forth for securing the same in a closed position.

It is well known that with most devices of this kind now in use, little or no provision is made in the construction to hold the door or gate tight against the casing to prevent rattlin 1 Tie present invention aims to remed this defect in so constructing the hasp that it will at all times maintain the parts to which it is applied in close contact.

Another object of the invention is to render the hasp self-adjusting to compensate for the contraction or expansion of the parts to which it is applied. This construction will be found very advantageous whenused on gates, barn doors, or other out-buildings where exposure to the weather causes the parts to swell or warp.

With these and other objects in view, as will more fully hereinafter a pear, the invention consists in certain nove features of con-' structionand arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and "particularly pointed out in the appended claims,it being understood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages o the invention.

In the accompanying drawings :Figure 1 is a side view of the device showing it applied to a door or gate. Fig. 2 is a similar view showing a modification of Fig. 1. Fig. 3 is a still further modification applied to a door or gate. Fig. 4 is another modification.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

In the form shown in Fig. 1, the hasp proper is formed of engaging and attaching members suitably connected by a spring or the like. The sections are preferably formed of steel rod orother suitable material, and in the construction illustrated in Fig. 1, the engaging member is provided with the usual -into engagement with the hook 1 having a slight overhang 2, adapted to engage a fixed eye or staple 3 secured in a well known way to a door, gate or casing. The-shank 4 extends backward and away from the bight in the usual manner, and adjacent its free end is curved outwardly and inwardly to form an eye or loop 5 which is bent at right angles to the shaft 4, and lies in a plane with the bill 1. The attaching member is of the approximate length of'the diameter of the engagin member, and is provided with a shank 6 w ich is adapted to engage the eye 5, and its inner end is bent at right angles, and an eye '7 formed thereon which embraces the shank 4 of the engaging member. The outer end of the attaching member is curved outwardly and inwardly forming an eye or loop 8 for the reception'of an .eye bolt 9 which secures the hasp to a door, a gate or casing. Interposed between the eyes 5 and 7 and encircling the shank 4 of the engaging member is a coiled spring 10, the ends of which abut the inner faces of the eyes and normally tend to force the sections apart in the direction of their length. With this con- 7 struction it is obvious when the hook is a plied to a door or gate, it will purposely fie placed at a distance from the eye bolt 3 greater than the distance from its pivotal connection 9 to the hill 1, it being understood that the coiled spring 10 is not compressed. Thus, when it is desired to bring the hook eye bolt 3 the shank 4 is forced in the direction of its length against the action of the spring 10 until the bill enters the eye 3, as shown in Fig. 1. In this position there is a tendency of the device, due to the start of thespring 10, to force the door or gate into contact with the casing, thus at all times insuring a tight fit and thereby prevent rattling.

In the modification shown in F 2, the device is shown applied to a door 11 and casing 12. In this'case the engaging member is provided with a hook 1 and a slight overhang 2 approximately the same as shown in Fig. 1 and which are adapted to similarly engage an eye bolt 3 anchored or otherwise secured in the casing 12. The shank 4 extends in the usual manner back from the bill and shank, and its intermediate section is convoluted forming a spiral spring 10 and the endterminating in an attaching member having an eye 8 adapted to embrace the eye bolt 9 anchored or otherwise secured to the door or gate 11. The function of this construction is similar to that of the hasp already described, the spring sect1on 10 performing a function similar to the sprmg 10 of Tn the construction shown 1n Fig. 3, a resilient rod, preferably formedof steel or other suitable material is intermediately curved or convoluted, for a portion of its len th, to form a s ring 10. The opposite en s of the rod are t en lnserted in the spring and emerge from the opposed ends thereof,

forming engaging and-attaching members 4 of wind.

The operation of the construction is similar to that already described, with the exception that the longitudinal adjustment of the members is limited to a less extent than the construction already disclosed. By reference to Fig. 3 it will be readily seen that an extended pull on the member 4 will result in the compression of the s ring 10, and, at the same time, have a ten ency to narrow the loop 5 formed on the end of the member 4 and embracing the engaging member 6. This construction of the loop will cause the latter to gri the attaching member 6 and prevent furt er compression of the spring, and consequent lengthening of the devlce J In the construction illustrated in Fig. 4, the engaging member is provided with the bill 3 and shank 4* extending backwardly and terminating in a loop or eye 5' bent at right angles to the shank. A portion of the shank 6 adjacent one end of the attaching member is curved outwardly and inwardl forming an eye 8 and the end brought para lel to the shank 6 formin a sto for the loop 5 of the engagin mem er 'l he shank of the attaching-mem er is inserted through the loop 5 and the end terminating in a loop 7 enclrcling the shank 4 of the engaging member. A helical spring 1O having its ends anchored in the loops 5 and 7 encircles the shanks 4 and 6 and normally holds the loop 5 in contact with the free end 9 of the attaching member as illustrated.

What is claimed is 1. A hasp embodying engaging and attaching members havin their 0 posed inner terminals yieldingly held for re iative longitudinal movement.

2. A hasp embodying engaging and attaching members and. a spring connecting the opposed inner terminals of said members.

3. A hasp having an enga ing member with an eye formed on one en thereof, and

an attaching member adapted to be inserted in said'eye, and having a loop on the end thereof ada ted to embrace the en aging member, an a coiled spring held byt e enga 'ng member.

11 testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two Witnesses.
